Definitions
- FIG. 8 is a schematic structural diagram of an apparatus for compressing a nested protocol packet header according to an apparatus embodiment of the present invention.
- the executive subject of each foregoing step may be a relay, while the sending end may be a user equipment (UE), and a receiving end may be a base station; or the sending end is a base station, while the receiving end is a user equipment; or the sending end and/or the receiving end is another relay.
- UE user equipment
- the sending end is a base station
- the receiving end is a user equipment
- the sending end and/or the receiving end is another relay.
- the original CRC field and MSN field in the IP/UDP/RTP protocol compressed packet header at the internal layer are already set to null, and certainly, the CRC field and/or the MSN field in the IP/UDP/RTP protocol compressed packet header at the internal layer may also be deleted. In this way, a processing delay and a load of the protocol packet header may be reduced, and efficiency in compressing the protocol packet header may be improved.
- information recorded in the CRC field and the MSN field may be reserved in the IP/UDP/RTP protocol compressed packet header.
- the base station After receiving the data packet which includes the nested compression protocol packet header, the base station performs decompression and the CRC check on the data packet according to the known context information. In this case, if it is learnt by the CRC check that an error exists in the received data packet, it indicates that an error occurs in the process of sending the data packet by the relay to the base station, and the base station sends a message to the relay to require that the relay resend the data packet.
